But which one's which?  We spotted Lindsay Lohan and girlfriend Samantha Ronson leaving Madison Square Garden in New York City after catching one of Madonna's concerts on the Sticky and Sweet Tour.

Lindsay has hinted that she will dress up as veep nominee Sarah Palin for Halloween.  Rubber masks of Palin's face have been flying off the shelves and in addition to LiLo as Sah Pah, Sam might dress up as Todd Palin!  I'm sure Todd Palin never imagined a life where he might be so famous, lesbian djs would pretend to be him for Halloween.
